EASY Series UBM Applicators

UBM Easy Series: The first and only ZERO MAINTENANCE applicators in the world for Polyurethane Reactive (PUR) adhesives in cartridges.

The UBM Easy Series of applicators with “melt on demand” technology provides the ideal solution for melting and applying small quantities of PUR adhesives in a variety of sectors such as paper-transformation, bookbinding, textiles, and assembly. These highly innovative applicators are easy to use and flexible enough to adapt to different production needs, with low impact maintenance operations and costs. The applicators are quickly installed and easily programmed, with suitable security standards. Exceptional reliability and complete integration into any existing automatic line guarantee great application versatility that helps increase productivity and reduce the amount of wasted adhesive. The new microprocessor manages all system operations from thermoregulation of the various sections to programming glue lines. Other specifications are: Economy function, Clock, Weekly Program, Automatic ON-OFF function, Over-Temperature Alarm, Delayed Cut-out for Temperature Set Point, and Heating Cycle Management.

LCD DISPLAY AND INNOVATIVE PROGRAMMINGThis feature provides images of all sections of the machine (tank, pipes, and guns) and the relevant parameters, making it extremely simple to program the system even for non-specialist personnel. There are no problems involving codes or foreign languages to interpret. A notification area constantly and dynamically monitors the machine’s status. Specific messages are displayed for alarms, errors and malfunctions. A rotary switch is used to set all system parameters very easily.

PUR CARTRIDGESThe system uses mono-component PUR adhesive cartridges with a diameter of 125-150 mm and maximum height 200 mm. The cartridge fits directly into the tank with its aluminum inliner and there is no need to add inert gas or dried air. This procedure prevents harmful vapors from being released during the cartridge change phase – a simple, quick and completely safe procedure, thanks to a special system.

ZERO MAINTENANCEAll parts of the applicator can be inspected easily because of a practical body design system that opens quickly to facilitate cleaning, especially around the pressure plate area. Thanks to this innovative construction method the entire plant requires almost no maintenance, with clear savings in terms of time and money.

GEAR MOTORThe applicators are fitted with variable speed AC motors run by horizontally positioned inverters. This arrangement minimizes overall dimensions and provides easy access both for inspection and maintenance, through a quick connector and an easy-to-open body system.

HIGH PRECISION GEAR PUMPThe system is fitted with very precise and reliable gear pumps made of fully tempered high speed steel (HSS) with different flow rates. Like the other internal parts of the applicator, the pump is easy to remove in case of maintenance or replacement.

BY-PASS VALVE FOR PRESSURE REGULATION AND RELEASEThis valve maintains the pressure constant with machine settings and ensures the utmost safety during system operation by releasing the pressure of the adhesive inside the plant automatically and safely, even in the event of an emergency.

PRESSURE CONTROL GAUGEThe applicator display shows the output pressure of adhesive at the manifold, monitored by a sophisticated control system. The display can be read like a traditional digital pressure gauge, indicating the pressure of the adhesive in bars.

“MELT ON DEMAND” TECHNOLOGYThe melt on demand melting system only heats the quantity of adhesive required. A piston is activated that presses the cartridge onto the melting plate to feed the manifold. This system makes it possible to reduce thermal stress to a minimum, protecting the remaining adhesive that is perfectly preserved in its original packaging.
